The heated water is then passed through a filter, which separates theV balance of the lime, as Willbe more fully described on referenceto the accompanying drawings, wherein;

Figure 1 represents a central sectional elevation of my improved apparatus, and

Figure 2 represents a section on the line :v-x of figl.

G represents a pipe, con1munioating with tlleflter H, which latter consists of a sack of woven fabric, arranged within the tub I, containing sawdust and straw. lK representsa man-holev cover, for the top of the heater, which is secured to the same by the bolts a and nuts b, the lower end s of the bolts being bent at right angles, so that when the cover is set down to its. place, they.n1ay he tumed partly aro'nnd, so as to take under the lower side of the head, and bo screwed up tightly to it, the pins-O, on the under side ot' the head, and C', on the under side ofthe manhole-cover, preventing the boltheads from'turning too far each way.

I claim as new, and desire Patentf The arrangement ofthe supply-pipe E, exhaust-pipe C, ingress-pipe B, water-delivery pipe G, Afilter I, and vessel A, substantially as herein set forth. Y
